For more than a decade, scientists have observed “ship tracks” in natural-color satellite imagery of the ocean. These bright, linear trails amidst the cloud layers are created by particles and gases from ships. They are a visible manifestation of pollution from ship exhaust, and scientists can now see that ships have a more subtle, almost invisible, signature

A deep and persistent drought struck vast portions of the continental United States in 2012. Though there has been some relief in the late summer, a pair of satellites operated by NASA shows that the drought lingers in the underground water supplies that are often tapped for drinking water and farming.

An oversized semi-trailer truck carrying NASA’s Landsat Data Continuity Mission (LDCM) has arrived at its launch site at Vandenberg Air Force Base in California in preparation for launch. This NASA and U.S. Geological Survey mission will continue a 40-year record of measuring change on the planet from space. LDCM is the eighth satellite in the

A new analysis led by NASA’s Jet Propulsion Laboratory, Pasadena, Calif., has estimated how much the growth of plants worldwide is limited by the amount of nutrients available in their soil. The maps produced from the research will be particularly useful in evaluating how much carbon dioxide Earth’s ecosystems may be able to soak up

In the United States, approximately 53% of the population lives near the coast. Thermal expansion of the oceans and mountain glacier melting are the greatest contributors to present sea level rise. Continued global climate change could increase the intensity and frequency of storms along the East Coast, causing serious flooding. Damages to coastlines and infrastructure

Farmer Gary Wagner walks into his field where the summer leaves on the sugar beet plants are a rich emerald hue — not necessarily a good color when it comes to sugar beets, either for the environment or the farmer. That hue tells Wagner that he’s leaving money in the field in unused nitrogen fertilizer,
